What should I do if my computer does not start?

❑ Make sure your computer is securely plugged into a power source and
turned on and the power indicator light is lit.
❑ Make sure the battery pack* is installed properly and charged.
❑ Disconnect all connected USB devices (if any), and then restart your
computer.
❑ Remove any extra memory modules you may have installed since
purchase, and then restart your computer.
❑ If your computer is plugged into a power strip or an uninterruptible power
supply (UPS), make sure the power strip or UPS is plugged into a power
source and turned on.
❑ If you are using an external display, make sure it is plugged into a power
source and turned on. Make sure the brightness and contrast controls
are adjusted correctly. See the manual that came with your display for
more information.
❑ Unplug the power cord or the AC adapter, and remove the battery pack*.
Wait three to five minutes. Reinstall the battery pack, plug the power cord
or the AC adapter, and then press the power button or slide the power
switch to turn on your computer.

not use the computer for at least one hour.
